I built all my PCB's with DipTrace https://diptrace.com/ There's a free version of it that allows for 300 pins. You can also request a free non-profit lite license that allows for slightly larger projects up to 500 pins. I had to get that for FMC PCB board.

For manufacturing, I'll either use OshPark here in the States for small boards/small ordershttps://oshpark.com/

or EasyEDA/JLCPCB in Shenzen China for larger boards/large orders. https://jlcpcb.com/quote
